Egg identification

[hoosierhens101]

I have a Lavender Orpington Rooster and 2 LO hens. I have 9 other brown egg layer hens. Has anyone invented something that marks the eggs when it is laid with a color so I can tell which eggs the Lavenders laid? We want to hatch some. Or what is the least disruptive way to know which eggs came from my Lavenders? Thanks

What about housing the LO's separate from the other chickens? That way you'd be able to pull just the LO eggs for hatching.

You can put food coloring on/in their vents and when an egg is laid it will be marked.
